The latest episode of the DisneyDish with Len Testa and Jim Hill, they opined that they both believe WDW AP's are going away(as we know them). They floated the idea that the new pass might be something akin to you can only use it on specific days(Wednesday's) or whatever. So if you want to pay once and go you will be shoehorned into specific odd days of the week, making it almost impossible to make a standard vacation out of it and to appeal more to local residents to fill the parks on less crowded days(if those exist anymore). It would also incentivize people to start their vacations on odd days to try and pick up a day or two thereby balancing the surge they normally get when most people start their vacations.
Point is, AP's as we know them, 'buy a single ticket literally go any day or every day you want for the rest of the year' , is almost certainly gone. I would bet everything I own on that, and Jim Hill and Len Testa seem to agree.
